Hi all,
I'm getting the above error while trying to show entities with lazy-loaded
properties.
I have a SLSB in which I retrieve an Entity from the Database.
The EntityBean is as follow:
| public class Walzen implements java.io.Serializable {
| .
| .
| .
| private Werkstoffe werkstoffe;
| .
| .
| .
| @ManyToOne(cascade={},
| fetch=FetchType.LAZY)
|
| @JoinColumn(name="WERKSTOFF", unique=false, nullable=false,
insertable=true, updatable=true)
|
| public Werkstoffe getWerkstoffe() {
| return this.werkstoffe;
| }
| .
| .
| .
| }
|
where Werkstoffe is also an EntityBean:
| @Entity
| @Table(name="WERKSTOFFE"
| , uniqueConstraints = { }
| )
|
| public class Werkstoffe implements java.io.Serializable {
| .
| .
| .
|
| @Column(name="NAME", unique=false, nullable=false, insertable=true,
updatable=true)
|
| public String getName() {
| return this.name;
| }
| .
| .
| .
| }
|
|
In my SessionBean I do a simple "select w from Walzen" in a @Factory-Method.
As I try to show the name-Attribute in the JSP like:
| <f:view>
| <t:dataTable id="walzen" var="walze" value="#{walzenliste}">
| <t:column>
| <h:outputLabel value="#{walze.hydronummer}">
| </h:outputLabel>
| </t:column>
| <t:column>
| <h:outputLabel value="#{walze.werkstoffe.name}">
| </h:outputLabel>
| </t:column>
| </t:dataTable>
|
|
| </f:view>
|
I get the above Error.

Where am I wrong? Do I have to set the fetchtype to EAGER? But for what is LAZY
then? Shouldn't Seam/JSF know when to load the Data from the Werkstoffe-Table?
Thanks for any help!
Stefan
